After 20 Years, It's Clear NAFTA Has Failed To Deliver Promised Benefits; So Why Trust TPP, TTIP Will Be Better?

Both TPP and TAFTA/TTIP are based on the premise that by boosting trade and investment, general prosperity will increase too. And yet, despite the huge scale of the plans, and their major potential knock-on effects on the lives of billions of people, precious little evidence has been offered to justify that basic assumption. To its credit, the European Commission has at least produced a report (pdf) on the possible gains. But as I've analyzed elsewhere, the most optimistic outcome is only tangentially about increased trade, and requires a harmonization of two fundamentally incompatible regulatory systems through massive deregulation on both sides of the Atlantic. In any case, the much-quoted figures are simply the output of econometric models, which may or may not be valid, and require extrapolation to the rather distant 2027, by which time the world could be a very different place.
